| Abstract: |
Elemental abundances of the chemically most primitive stars are
believed to record the nucleosynthesis yields of the first generations
of stars, their mass distribution, evolution, and nature of their
supernova explosions. This paper reviews recent progresses in searches
for extremely metal-poor stars ([Fe/H]< -3) in the Milky Way halo and
studies of their chemical abundances, in particular our recent efforts
of follow-up spectroscopy with the Subaru Telescope for candidate
metal-poor stars discovered with SDSS/SEGUE. The metallicity
distribution of extremely metal-poor stars ([Fe/H]< -3) and fraction
and nature of carbon-enhanced stars among them are discussed. |
